SCRIPT TO ADD A SECONDARY DNS

[djgreek]

HI ALL,
I RECENTLY STARTED WORK AT A SCHOOL I AM STILL TRYING TO LEARN THE ROPES.
THE PREVIOUS NETWORK ADMIN USED STATIC IP ADDRESS FOR EVERYTHING.
i HAVE RECENTLY INSTALLED A DHCP AND IT IS WORKING
I ALSO CONFIGURED A SECONDARY DNS WORKING AS WELL.
ALL NEW CONECTIONS WORK.
I NEED TO CHANGE THE OTHER 500 COMPUTERS.
CAN SOMEONE HELP ME CHANGE THE SECONDARY DNS ON ALL MACHINES OR SOMEONE HELP ME WITH A SCRIPT THAT WILL CHANGE SETTING TO USE DHCP

If your clients can run a startup script from group policy then

netsh interface ip set address "Local Area Connection" dhcp

will do the job as long as they're not wireless. I think if they are wireless you need to change 'local area connection' to 'Wireless Network Connection'

From the spiceworks website: Simple Script to Enable DHCP on Network adapters - Script Center - Spiceworks Community

The script is a VBS Script

' Enable DHCP

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Set colNetAdapters = objWMIService.ExecQuery _
    ("Select * from Win32_NetworkAdapterConfiguration where IPEnabled=TRUE")
 
For Each objNetAdapter In colNetAdapters
    errEnable = objNetAdapter.EnableDHCP()
Next

Welcome to edugeek, there are several approaches using netsh or vbscript, Cromertech's solution is probably the easiest for you to implement.

VBScript: Reset DNS to DHCP Assigned

PS please do not write all in CAPS it is very hard to read!
